'concede victory'&'concede defeat'
I've found the phrase 'concede victory' appealed in several news reports clearly meaning the same as 'concede defeat'

Is “X conceded victory” a brief version of "X conceded victory to Y"?
If not, how can "concede victory/defeat" mean exactly the same?yes that seemed strange to me too
but the phrase definitely appealed in serious news reports not once but several times at least as I have seen.
I can easily google it, and find you one

Answer

Concede means Admit.

I've never really seen "Concede Victory" but I have seen "Concede Defeat"
 they don't mean the same thing.  "They conceded defeat." Meaning they admitted that they lost. No one would necessarily need to "admit" victory, because it's usually pretty evident.
